This photo clearly shows the warp in the sides of my teardrop shaped hoop which will form the sides to my sound-box and affect the shapes of my sound-board and back-board. I need to eliminate this warping before I can ever hope to have a nicely shaped sound-box. So, I'm planning re-soak and re-shaping using a modified forming-rack.

Hi Anders,

I'm not familiar with the technique, but it sounds plausible. Would have to more research an/or watch a video of someone doing it. I'll keep it in mind for when I get back to the States. I can't access Youtube and most other video hosting websites as they are all blocked in China. But a discussion of the technique with photos and possibly a CBN hosted video would be of interest to me and other "box guitar builders" who want to try building more exotic box shapes with bent wood sides.

Hi Anders,

I'm not sure I understand you. The alternative build technique I've been thinking of is to cut the side board into several shorter lengths, bend those, and then glue them together using head and tail blocks, corner blocks, and the like, and I may try this on some future build, but likely with a somewhat more complicated body shape. By "laminating" do you mean to bend a number of lengths of thinner wood (like 2mm plywood veneer), shape them and then glue the together to form the continuous changing curved sides? That sounds pretty hard to do. It seems easier to draw out a pattern on paper of my body shape, then use a jig saw to cut the identical shape into 3 planks of wood, then mount them one on top the other to make much more solid forming jig. The warping seems caused by the lack of support between the 8" drum hoop part of my forming rack and where the two ends of the teardrop shaped board are clamped down. I'm currently re-shaping the teardrop board with a modified forming jig setup which so far looks to have eliminated much of the warp. Will know in another day when I release it from the rack.
